I have been trying to get into hammer. but I cannot make a functioning map. every time I tried I got the same error message. I have looked it up apparently it's a leak, but the skybox was hollowed I don't know how there could be a leak. is there something I'm missing.
just a question: for what game base or mod you're trying to build? also in case of a leak, the compile log will say to you or you can also go to "Map > Load Pointfile" which will show you a line of the leak is happening. and wgat unbeatwater said in the replies, always make sure your gameinfo.txt/your hammer configs is set correctly (.exe, directory, bsp vrad vvis etc)
just for half-life 2. I am using hammer++ so I'm pretty sure it covers the episodes. thanks for the info.
I haven't done mapping in a while, so I might be wrong, but it looks to me as if it built just fine, but couldn't copy the file. See if there is a BSP file called "pleasework.bsp" right next to your VMF map file, if it exists, copy it to the game's "maps" directory.
Thank you it worked.
